: VNOM2 refers to the nominal output voltage level for VOUT2 as defined by the Ordering Information section.
: Dropout Voltage is defined as the differential voltage between input and output when the output voltage drops 100mV below the
regulation voltage at 1V differential voltage.
: LDO current limit is defined as the output current at which the output voltage drops to 95% of the respective regulation voltage. Un-
der heavy overload conditions the output current limit folds back by 30% (typ)
